Jakarta is sinking with 40% of the city and most of North Jakarta under sea level. By 2030 the city is likely to be under water at the pace with which it is sinking into the Java Sea. Jakarta's problem comes from years of overbuilding, migration from rural areas, with no adequate system for supplying piped water. Many of the wells illegally built by developers, with 97% of the city in concrete preventing resupply of aquifers from heavy rains, have aggravated the sinking. The aquifers acted as a kind of foundation for Jakarta. Climate change is another factor adding to the problem.

As a result a city that gets heavy rains and rivers coming in from the mountains with water, is now flooded frequently, unlike an earlier period when the Dutch used canals and dikes to manage the water flow. Efforts to prevent developers from draining the aquifers on which Jakarta rests have failed. North Jakarta is the worst affected and this area has many of the poor slum areas of the city. Evicting the tenants living there to clear the debris and clean up the canals and rivers has failed. The former governor of Jakarta, Mr Purnama known as Ahok, of ethnic Chinese origin, lost the election to Islamic parties and their allies following his efforts to clean up the area and take action to replenish the aquifiers.

This NYT report is based on interviews with residents of the kampungs or settlements of people from rural areas within North Jakarta. A Dutch hydrologist Mr Brinkman is a expert on Jakarta's water systems. He says eviction is not the answer by itself but some effort to move people is needed and North Jakarta needs to be restored to its original mangrove situation, which would allow replenishing of underground water. Giving Jakarta a more stable foundation. About 30 million people live in this fast growing city and a lot depends on how Indonesians can prevent the city from sinking further into the Java Sea.
